Business Systems Analyst (BSA) to join our Enterprise Applications team.

Reporting directly to the Head of IT and Security, you will be instrumental in designing the business process flows that drive our company. You will be responsible for bridging the gap between key business stakeholders and our tech stack, ensuring our systems and environments support the unique complexities of a scaling fabless semiconductor company.

• Semiconductor Business Architecture
• Design & Deploy Flows:
  Architect and implement end-to-end business flows from scratch. You will define how a wafer moves systematically from a Foundry through OSAT (Assembly/Test) to a finished good.
• Process Mapping:
  Translate complex physical manufacturing processes into digital workflows, covering Yield Management, RMA, and Subcon Manufacturing.
• ERP & PLM Process Management
• System Process Ownership:
  Serve as the functional process expert for Net Suite and Arena PLM. You will ensure the business can run these processes flawlessly as we scale.
• Finance & Accounting Support:
  Configure and optimize Finance modules, focusing on Cost Accounting, Fixed Assets, Order-to-Cash, and Procure-to-Pay processes within a manufacturing context.
• Supply Chain Operations:
  Configure flows through applications tracking, Inventory Valuation, and Demand Planning.
• General BSA & Integration Work
• Requirements Gathering:
  Act as the liaison between business stakeholders and technical teams. You will translate "semiconductor speak" from engineers and Supply Chain into technical specs for developers, and "finance speak" into logic for system configuration.
• Integration Oversight:
  Manage data flows between our internal systems and external parties (foundries, OSATs/Customers).
• Documentation & Training:
  Create robust documentation for new processes and lead training sessions to ensure user adoption across the company.
• Testing and Support:
  Lead and execute User Acceptance Testing (UAT) and provide feedback to the administrators. Provide hypercare after launch and general support for systems.
• Partner Ecosystem:
  Work closely with our vendors and partners to understand and design solutions.

• Minimum of 8 years of experience as a Business Systems Analyst
• Bachelor's degree in business or an IT-related field.
• Semiconductor
  
  Experience:
  
  You must have prior experience in the semiconductor industry. You understand the chip lifecycle, from tape-out to packaged unit, and the specific data requirements of a fabless model.
• Net Suite Expertise:
  Deep functional knowledge of Net Suite is required. You should be comfortable with how Net Suite works, its capabilities, and best practices.
• Proven Builder:
  You have been a BSA before and have a track record of setting up business flows from scratch or executing major system implementations. You are not just maintaining existing SOPs; you are writing them.
• Domain Versatility:
  You are comfortable pivoting between Supply Chain (BOMs, WIP, Logistics), Finance (COGS, Revenue Recognition, Billing), and other teams daily.
• Process Modeling:
  Ability to visualize and document flows to drive consensus among stakeholders.

• Experience with IPaaS/Integration tools (e.g., Celigo, Boomi) for connecting Net Suite to other platforms.
• Experience with Arena PLM
• Experience with EDI…
